lM PROVEMENT IN HEATING-S TOVES The Schedule referred to in theseLetters Patent and making part of the same.

To all whom it may concern Be it known that I, ISAAC Dn Haves, of thecity and county of Allegheny and State of Pennsylvania, have invented anew and useful Improvement in Heating-Stoves; and I do hereby declarethat the following is a full, clear, and exact description thereof,reference being had to the accompanying drawing and to the letters ofreference marked thereon.

The nature of my invention consists in the arrangement of afuel-chamber, fire-chamber, heatchamber, and lines, constructed,arranged and operating as hereinafter described.

To enable others skilled in the art to make and use my invention, 1 willproceed to describe its construction and operation.

In the accompanying drawing which forms part of my sp .*.cilicatiou V ligure l'is a side. elevation of my,im n'ovement in heating-stoves.

Figure 2 is a front; elevation of the same.

Figure 3 is a vertical section of the same when out through at line 9 offig. 2.

Figure 4 is a top view or plan of the stove;

in the accompanying drawing- A represents the base of the stove, whichis provided with an ash-box, h, lines 1', gatheririg-chamber ..r forheat, dust, and smoke, and pipe J.

Upon the base A is a case,B, which is provided with a fire-chamber, U.and its grate m, and also with a fuel-chamber, I), and its lid K, whichis provided with a pivoted register, I.

As the construction andarrangement of the several parts of myimprovement,will be r adily understood .from the ioregoing description,and by reference to the accompanying drawing, I will therefore proceedto describe the operation. which is as follows:

The lid K is removed from over the fuel-chamber 1); a lire is kindled inthe fire-chamber U; the chamher 1) is then lilled with the desired fuel,and the lid K is then placed over the chamber D, as shown in theaccompanying drawing.

The smoke and heat will pass over the upper edge of the walls of thelire-chamber O, and pass down through the fine ff into the fines i, andthen back into the chamber a, from which it passes out through pipe J.

When the tire in chamber 0 has thoroughlyignited the fuel in it, andthat portion of it which is at and is radiated into the room by the caseB of the stove.

Itwill be observed that the stove has a double draught of air, one upthrough the fire-grate on, and the other down through the fuel inchamber 1); these two draughts meet at x", and thereby cause thegreatest heat to .be at that point, so that the air, before coming incontact with the smoke, is heated to avcry high degree, which gives toit a property which will aidgreatly in the consumption of the smoke.

By constructing the stove as hereinbefore described, the heat isdiffused through all parts of the stove, and a large portion of the heatpasses down through the base A, whereby that portion of the stove whichis next the floor of the room radiates its proper portion of heat.

The arrangement of lines i in the base causes the heat and smoke to passin a thin and continuous sheet overthe top of the walls of thetire-chamber 0 equally at all points, so that the heated air, coming upthrough the grate ill and down through the fuel in the chamber 1), isdistributed in such manner as best adapted to aid and insure perfectcombustion.

The fuel, as it burns down in chamber 0, sinks down in chamber D, sothat the tire is constantly supplied with heated fuel. l

When it-is desirable to reduce the heat of the stove, the inlets of airare closed or partially closed.

The grate is cleaned by moving the lever a sidewise, imparting to it areciprocating motion.

Having thus described the nature, construction, and operation of myimprovement,

What I claim as of my invention 1s-- The arrangement of the chambers D Ge, register I, and fluesfi and chamber x, constructed, arranged, andoperating asherein described, and for the pur-- pose set forth.

ISAAC DE HAVEN.
